JOURNAL OF ENTREPRENEURSHIP IN EMERGING ECONOMIES

Abstract
Purpose The research aims to examine the underlying factors of entrepreneurial intentions among seniors. In this vein, it evaluates the role of social context proxied by the human development index (HDI) along with individual characteristics towards these initiatives. Emerging economies deliver great potential for income generation swiftly approaching the standards of their developed counterparts. Their present ageing trends severely threaten growth prospects because of workforce withering. European insights will help anticipating constraints through alternative models of human capital allocation. Design/methodology/approach Four logistic regressions were run to address hypotheses in test, relying upon the global entrepreneurship monitor - adult population survey. Estimations include 20,386 individuals from database and 21 European Union countries. Ex-post robustness checks corroborate the global significance of the proposed model. Findings Empirical findings reinforce the importance of the macroeconomic context among senior endeavours and the non-linearities in terms of the age effect. Moreover, context can help eroding gender gaps in this field and refine the opportunity perception These results go in line with the literature and extend the importance of promoting a favourable ecosystem. Promotion of senior endeavours must consider smart policy packages encompassing the individual singularities as this age range will be too important to be wasted. Senior entrepreneurs are key to the latent job market crisis, needing to be encouraged through positive discrimination. Research limitations/implications Originally, by incorporating an exogenous variable encompassing the role of the entrepreneurial context, this study contributes academically to evaluating the determinants of entrepreneurial activity among the elderly. In addition, the development of cohorts highlights the specific importance of individual characteristics in entrepreneurial propensity in each context. The heterogenous results proves the ineffectiveness of "one sizes fits all" policies. Practical implications This research reinforces extant literature, notwithstanding the empirical refinements implemented brought up two additional perspectives: complementing previous towards the relevance of HDI cohorts along with the non-linearities of the effect of age. Learning from the European context and acknowledging efficacy of policy instruments will avoid serendipitous actions or failures, enhancing promising ecosystems such as emerging economies. Originality/value The study academically contributes to the appraisal of the determinants of entrepreneurial activity among seniors, thus, in an original way, by incorporating an exogenous variable to appraise the role of the context. Development cohorts evidence the existence of singularities in entrepreneurial propensity and individual characteristics according to their levels, such that policy actions should consider their differences.

The Contribution of Local Agents and Citizens to Sustainable Development: The Portuguese Experience

SUSTAINABILITY

Abstract
The achievement of the 2030 Agenda implies a shared responsibility in the implementation of the Sustainable Development Goals (SDGs). Local government, in particular municipalities, is closer to citizens and, therefore, better placed to respond to the needs of each region. This study intends to explore initiatives promoted by civil society, businesses, and local organizations in the context of each municipality in Portugal to address the sustainable development goals established in the 2030 Agenda. It adopts mixed methods to quantify the impact of these initiatives in the territories and qualitatively explores the inherent characteristics associated with each project. The findings show that there are significant asymmetries in the number of projects in the Portuguese regions and that there is a moderately positive correlation between the number of projects and the municipality's population density and GDP. It was also found that the projects focus mainly on areas such as SDG1, SDG1, SDG11, and SDG13. The projects are mainly characterized by offering platforms for collaborative work among the various stakeholders, seeking to meet the challenges of combating social exclusion, and supporting environmental education. Above all, this study offers implications for local agents to work in networks and establish synergies between projects that may lead to greater territorial coverage and contribute to reducing the socioeconomic asymmetries that exist in the country.

<i>E</i>-<i>MANAFA</i>: Energy Monitoring and ANAlysis tool For Android

Abstract
This article introduces the E-MANAFA energy profiler, a plug-and-play, device-independent, model-based profiler capable of obtaining fine-grained energy measurements on Android devices. Besides having the capability to calculate performance metrics such as the energy consumed and runtime during a time interval, E-MANAFA also allows to estimate the energy consumed by each device component (e.g. CPU, WI-FI, screen). In this article, we present the main elements that compose this framework, as well as its workflow. In order to present the power of this tool, we demonstrate how the tool can measure the overhead of the instrumentation technique used in the PyAnaDroid application benchmarking pipeline, which already supports E-MANAFA to monitor power consumption in its Android application automatic execution process.

Abstract
This study aimed to validate the Patient Health Questionnaire (PHQ-8) in a sample of military personnel, through the analysis of psychometric properties, reliability, and confirmatory factorial analysis. The questionnaire consists of 8 items that allow the assessment of depressive symptoms. The sample included 127 Portuguese military personnel aged between 21 and 78 years old. The results revealed a good internal consistency (alpha=.90) and good adjustment indices (chi 2/df=1.332, GFI=.956, CFI=.988, RMSEA=.051, SRMR=.30). In addition, convergent validity also showed to be good and composite reliability was .873. Thus, the PHQ-8 reveals good psychometric properties, being recommended for use in clinical practice and research with Portuguese military.

Defence Studies

Abstract
The European Defence Industry is undergoing profound changes. Industrial activity is now operating on a quintuple helix innovation model with the deep involvement of universities and governments in innovation. In addition, military innovations are being transferred to civil society, with increasing attention paid to the environment. In the first stage, we report on the state-of-the-art of existing research using PRISMA protocol. The PRISMA technique is widely accepted by the academic community for its ability to discover concepts, ideas, and debates about the defence industry. In the second stage, we present a case study involving the Portuguese Defence Industry, for which multiple data collection sources were used to ensure triangulation and corroboration. The results show that, in the light of the quintuple helix innovation model, it was possible to bring applications from theoretical discussion to real life. Moreover, within the scope of the triple helix, it was possible to develop, produce and test military products, allowing to improve the military capacity of ground forces. In the future, ecological concerns will likely increase, so we suggest a greater focus on this area of research.
